Step 3
Here i am going to explain how to create a rating control in ASP.Net with Bootstrap.
Step 1
Download files from github.com.
Step 2
Open Visual Studio, add your downloaded file into your project .
- <head runat="server">
- <title></title>
- <link href="Bootstrap/css/bootstrap.min.css" rel="stylesheet" />
- <link href="Bootstrap/css/star-rating.css" rel="stylesheet" />
- <script src="http://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
- <script src="Bootstrap/js/star-rating.js"></script>
- </head>
Now call your rating control. Before calling your rating control please learn how to use Bootstrap from my previous article.
- <div class="row">
- <div class="col-lg-12">
- <input id="input-21a" value="0" type="number" class="rating" data-symbol="*" min=0 max=5 step=0.5 data-size="xl" >
- <hr>
- <input id="input-21b" type="number" class="rating" min=0 max=5 step=0.5 data-glyphicon="false" data-star-captions="{}" data-default-caption="{rating} Stars" data-size="lg">
- <hr>
- <input id="input-21c" value="0" type="number" class="rating" min=0 max=8 step=0.5 data-size="xl" data-stars="8">
- <hr>
- <input id="input-21d" value="2" type="number" class="rating" min=0 max=5 step=0.5 data-size="sm">
- <hr>
- <input id="input-21e" value="0" type="number" class="rating" min=0 max=5 step=0.5 data-size="xs" >
- <hr>
- </div>
- </div>
Here, value is your filled start on page load, min is the minimum star value, max is the maximum star or maximum rating, data-size is your rating control size.

Step 4
Now we can see how to get the rated value from this rating control using jQuery as in the following:
- <script>
- $(document).ready(function () {
- $("#input-21b").on("rating.change", function (event, value, caption) {
- alert("You rated: " + value + " = " + $(caption).text());
- });
- });
- </script>
Let's see how to get the rated value from code behind in C#. Add one hidden field in your design page and assign your rated value into your hidden field.
- <asp:HiddenField ID="hdfRatingValue" runat="server" />
- <script>
- $(document).ready(function () {
- $("#input-21b").on("rating.change", function (event, value, caption) {
- var ratingValue = $('#<%=hdfRatingValue.ClientID%>').val();
- ratingValue = value;
- alert(ratingValue);
- });
- });
- </script>
